The written form of Queekish consists of several thousand pictograms, each representing a single word or concept. Most Skaven know the most important pictograms, while only a few can recite them all. As new discoveries are made, new pictograms are devised. Many are so similar as to be indistinguishable to the untrained eye. Writing is accomplished by the use of a sharpened stylus or an extended claw. Many Skaven records were kept on wax or clay tablets, but the use of ink on parchment has become increasingly popular with the Grey Seers and Master Moulders.
